The carriage is constantly urged leftward by a springdrum or motor (not'-shown),-to which it is connected by a of escapementdevices which operate throng connecting mechanismjicomprising I a feedvrack lion the carriageandfwhich con-' stantly me sheswith a, v feedpinion 15 mount ed on a horizontal shaft 16 .su 'portedlon the bedplate. The feedpinion is ooselymount- ,ed on said shaftbut is normallyconnected to turn, therewith in printing direction throughdevicesconnectingsaidpinion with t a toothed escapement wheel 17 fixed to saidshaft 16. Said devices comprise a spring pressed pawl-18 pivotedto theescapeme'nt. wheel and which normally engages with the teeth ofithe feedinion 15. ;Theescapement wheel is normal y ogged or' prevented fromturnin by devices comprising a dog ,19 whereby t e carriage is held.frommoving from right to left under theimpulse of; its

the control ofthe iescap'ement mechanismiby i p a ve to Separate theawl-1 from the feed pinion l5, said devices comprising; a sleeve 20slidahly mountedon the e scapement wheel shaftiand providedwith flanges2 1 spaced apart near its rearv and -tion forward on the sto operatewith a pin 23 fixed to the pawl 18 and projecting rearward therefromthrough a slot in the escapement wheel. Said sleeve 20 is controlledfrom the novel tabulating mechanism by devices presently to bedescribed.

In order to make the tabulator mechanism as compact and unobtrusive as.possible, we preferably mount the column stops inside the machine, as itmay be termed in contrast with the usual mounting outside of themachine. To this end a pair of angular brackets 24 are arranged one neareach end of the carriage, beneath the rear bar 6-8 (Figs. 1 and 5). Thebrackets are formed with holes 25 which receive headed screws 26 wherebythey aresecured to the carriage and depend from its rear. At their lowerends the'brackets are, erforated to receive the reduced rounded aringportions 27 of a toothed stop bar 28, the ends of the reduced portionsbeing threaded to accom-' 'modate nuts. 29. It will be observed that thestop bar is covered by thecarriage and is slightly above the lowercarriage bearing. The stop bar is formed at its upper and lower faceswith kerfs or cuts 30 providing teeth at, letter space intervals, whichteeth receive between them a set of column stops 31. These column stopsare of ordinary-construction being U-shaped so asto fit over the'stopbar between the teeth at the top and bottom thereof and being providedwith rearwardly projecting stop faces 31. Pivotally secured at 32 to theside of each stop bar is a yoke-like spring member 33 terminating in endstops 34 and 35 (Figs.

1, 5, 7 and 8). When in inoperative poslbar each stop 31 is held by theco-operation of the stop end 35 with the lower corner of the stop bar 28in the position shown in Fig. 8,-this osi'tion corresponding with thatof most of t e stops in Fig. 5 and also-with that of the stop nearestthe observer in Fig. 1. Thus maintained'the stops arein inoperativeposition or unset as it is sometimes termed. To set these stops orposition them for co-op eration with the key actuated decimal stops theyare selectively slid rearward in a manner hereinafter described. Duringthis slidmg movement the spring or retaining member 33 swivels or turnsslightly on its pivot 32, enabling the-stop end 35 to clear the lowercorner of the stop bar and permit rearward sliding movement of the stop31 on said-bar until arrested by co-operation of the stop end 34 withthe top front corn'er of the stop'bar as shown in Fig. 7 In other words,the stops 31 are'projectible or slidable rearward 'on their support tooperative position and are also retractable or slidable forward on theirsupport to inoperative or unset position. The ,stop settlng andretracting means comprise key the machine.

which are associated with the key operated decimal stops.

The decimal or denominational stop devices are mounted on a tabulatorframe which in turn is .detachably mounted on Said tabulator framecomprises a casting 36 having a hooded top portion 37 and depending sidearms 38 which.

curve outward at their lower ends and are connected by an angular crossbar 39 (Fi s. 1, 2 and 3), Detachably secured to t e front upper portionof the "hood 37 by screws 40 is a comb plate 41 provided at its top witharib or projection '42, the front of said comb plate being provided withupper and lower combs 43 and 44 for 'guidin the decimal stops The lowerortion o the comb plate is undercut or 0 -set rearward from the upperportion. The frame comprising the casting 36 and the comb platel41supports a set of decimal stop levers as well as certain of the stopsetting and un-setting devices, all these parts being attachable anddetachable with the frame. When in place on the machine, the frame 36,41 rests on the top-of the frame bar 2, the ledge 2 at the top of saidbar 2 providing a convenient seat for the horizontal portion of thecross bar 39 of the frame. The bed plate or trough 12 is cut out toaccommodate the hooded upperportion 37 of the'detachable frame, thecut-outof said bed plate indicated at 45 being at the right-hand side ofthe escapement shaft 16.. The upper edge of the cut-out 45 is formedwith a square-cut groove or depression to receive the rib 42 at the topof the detachable frame 36, 41. After said rib has been fitted in itsgroove, thus securingthe upper end of the frame, the lower end portionor cross bar 39 receives headed'screws 47 which are threaded into theledge 2,'thus rigidly securing the detachable tabulator framev in place;The decimal stop levers 48, of which there are ten in the presentinstance, are vertically arranged within the frame or casting 36, theirupper end portions curving forward within the hood and terminating inforwardly extending heads or stop portions proper 49 which areadapted toslide through the combs 43 and 44 .and are guided therepivot-a1 supportthe stop levers'spread orfan laterally outward and their lower portionsare received in slots or guide openings indicated at 52 formed in aguide plate or comb 53 that is horizontally disposed and extends forwardbeneath the cross bar 39, the plate 53 terminating at its rear in anupstanding portion 54 which is secured as by rivets 55 to the rear faceof the vertically disposed portion of the cross bar 39. Above the crossbar each lever 48 is provided with a rearwardly projecting lug 56 overwhich fits the forward end of a coiled restoring spring 57, the rear endof said spring being housed in a hole 58formed in the vertical part ofthe cross bar 39, the rear end of the spring abutting against the part54 which covers the hole at the back. he springs 57 tend to swing thelower arms of the stop levers 48 forward and the upper arms backward,maintaining the stop blades or heads 49 in retracted or inoperativepositions within the hood 37 ,r the rear edges of the stop leversnormally resting against astop bar 59 secured within the hood. Thelower-ends of the stop levers 48 are curved rearward and slightlyforward, terminating in rounded noses'60.

(lo-operative with the noses 60 area set of key operated'slide rods 61,one'foreach stop lever 48, the slide rods being arranged within the basein parallelism and extending fore-and-aft of the machine, beingsupported at both rear and front by detachable supporting members.terminates at its rear end in'a hook-like portion' comprising aflattened vertically disposed upright portion 62 and a forwardlyextending horizontal guide portion 63. The

hook-like portions of the slide rods are supported and guided by aU-shaped guide bar 64 terminating in' cars 65 which receive screws 66that are threaded into bosses 2 on the cross plate 2. The upperand'lower edges of the cross portion'of theguide bar 64 are formedwithslots or depressions indicated respectively by the numerals 67, 68, thelower slots 68 receiving and guiding the rear portions of the slide rodsproper 61.

while the upper slots 67 support and guide the forwardly extendingportions 63 of the slide rods and prevent the rods from turning on theiraxes. Each upright flattened portion is opposite the associate nose 60against which it is ada "ted to act when-the rod 61 is slid rearwar .toactuate the associate lever 48. The front ends of the slide rods 61 aresup orted and guided by a sheet metal guide p ate or frame 69 "which incross section is of an inverted U-shape (Figs. 1 and 6). The guide frame69 is secured by screws 70 to thefront of the frame memher 3 of themachine, the screws being accessible through"holes' 71, formed in thefront portion or plate of the guide frame. The end portions of the frontplate or flange 69 are cut away so as .to expose theend portions of therear plate or "flange 69", these end portions providing tabs 72. Theupper Each slide rod" 61 cross portion ofthe frame 69 is inclinedforward and downward and has secured to it by screws 73 a slottedindexplate 74 under which may be arranged asuitable number strip containingindicia which are exposed through the slot in the plate 74. The-forwardends of the slide rods 61 project forward beneath the bottom edge of theframe plate 3 and receive finger pieces 7 5. 7 These nger pieces arecylindrical in shape and may be made of fiber, some suitablecomposition,or other desired material. The rear faces of the finger pieces 75 havemetal disks 76 pressed or otherwise secured in them, said disks havingtapped holes which co-operate with the threaded forward ends of theslide rods 61 to d'etachably-secure the finger pieces or keys 7 5 tosaid slide rods. The front flange or plate of the frame 69 is formedwith holes indicated .at 75 of a suitable size to permit of the passagetherethrough of'the keys'75', the rear end portions of saidkeys normallyresting on the bottoms of said holes which serve as guides for the keysas they slide through during operations of the tabulating mechanism.When one of the keys 75 is pushed in, its slide rod 61wil1 be'moved orslid longitudinally rearward, causing the'flat portion 62 to'pressagainstithe'nose 60 of the associate stop lever 48 and swing said leveron its pivot 50-, projecting its upper or stop end 49 forward into thepath of those of the column stops 31 which have been set or projectedrearward on their su porting bar 28.. The actuation of one of t edec'imal stop levers 48 by its key 75 is effective automatically to reease the carriage from the controlof its escapement devices, thereleasing means comprisin' ,as shown in Figs. 1 to 4, a universal bar 7arranged horizontally behind the levers 48 somewhatbelow their pivotalaxis. Said universal-bar is provided with up-turned ears 78 whichreceive'sc'rews 79 that fasten the universal bar to the lower ends ofarms80 comprised" in a supporting frame which further includes a crossbar 81 connecting the arms 80, said arms bein angularly bent from thecross bar whic extends across the set of levers 48 at' their front. Theup'per'ends of the arms 80 receive pivot screws 82 which are threadedinto the sides of'the arms 38 and provide a pivotal support for theframe 80, 81 and the universal'bar member 77, '78 carried thereby. Thelower ends of the arms 80 are squared off and rest in contact with theupper face of the universal bar 77 so that the latter is held in rigidrelationship with its supporting frame- The left-hand arm 80 has anupward extension 83 which is curved or bentleftward and terminates in ahorizontally disposed-finger or engaging portion 84 which fits betweenthe flanges 21 of the sleeve 20. When one of the stop levers 48 isactuated by its key 7 5 the lower arm of said stop lever swingingrearward about its pivot will contact with the front edge of theuniversal bar 77 swinging the latter rearward on its pivots 82 andcausing the finger 84 pressing against the forward flange 21, to slidethe sleeve 20 forward so that the beveled flange 22 acting against thepin 23, will lift the pawl 18 from the pinion 15, thereby releasing thecarriage. It will be observed from Fig. 1 that the universal bar 77 liesnormally some distance behind the rear edges of the levers 48 so thatthe universal bar will not be actuated until the latter part of thestroke of said levers, giving time for the associate stop 49 to bepositioned before the carriage is released. hen the tabulator key isreleased, permitting the actuated parts to be restored to normalposition, the tabulator universal bar 77 and connected parts willlikewise be restored to normal position through the operation of a.

coiled restoring spring 85, the rear end of which is seated in adepression 86 in the back wall .of the hood 37, the front end of saidspring fitting over a lug or projection 87 on the universal bar.

The stop setting devices whereby the column stops 31 may be projected orslid rearward on their supporting bar 28 into operative or set positionsare shown in Figs. 1, 2, 3, 6, 7 and 8 and comprise a crank arm 88terminating at its free end in a rounded nose which lies just forward ofthe lower branches of the column stops 31. Said crank arm is providedwith a hub 89 which fits over and is secured to the left-hand endportion of a horizontal rock shaft 90, having a stationary bearing 91projecting upward from the horizontal portion of the bed plate 12. Fixedto the right-hand end portion of the rock shaft 90 outside its bearingis a downwardly projecting arm 92 having a curved or cam face93 which isadapted to be acted against by the forwardly projecting nose 94 of astop setting lever 95. Said lever is of the general shape of the set oflevers 48 and is arranged at the right of said set and inside theright-hand casting arm 38 to which the lever 95 is pivoted at 95*. Thelower arm of said lever 95 is guided in a slot of the plate 53 andterminates in a nose 96 which is adapted to be acted on by the flatvertical portion 97 of a slide rod 98 which. also has an upper guidingportion 98*, said slide rod 98 corresponding in construction with theslide rods 61 and being disposed, at the right of said set of sliderods, the slide rod 98 being guided in the right-hand pair of guideslots 67 and 68. Thefront end portion of the slide rod 98 passes througha guide opening in the right-hand tab 72, being guided and supportedthereby. Fixed to the front end portion of the slide rod 98 is a stopset key or button 99. When the stop set key 99 is pressed in, its sliderod 98 willbe slid rearward, actuating the stop setting lever 95 andcausing the noselike upper end portion 94 of said lever, acting againstthe cam edge 93, to rock the shaft 90 and swing the crank arm 88rearward, causing said crank arm to press rearward against the lowerbranch of that particular column stop 31 which may lie opposite to saidcrank arm at the time, and sliding said stop rearward, or setting it ashas been described. It will be apparent that it is only necessary tomove the carriage endwise to position to bring the desired column stopsin line with the stop setting arm 88 and then to operate the stopsetting key 99, in order to set the desired column stops in position foruse. In Fig. 5 severalcolumn stops are shown as set or projected inposition for co-operation with the set of decimal stops, heads or blades49 when these are projected or swung forward into position as indicatedby the dotted lines at one of the decimal stops 49. It should here benoted that since the set of decimal stop levers 48 is off-set to theright of'the middle of the machine to clear the escapement devices, itis necessary correspondingly to elf-set the set of column stops, thisbeing done of course by adjusting the position of the column stop bar 28in correspondence with the off-setting ofthe frame 36 of the decimalstops. The universal bar 77 is cut away at its right-hand end at 77behind the lever 95 so that the stop setting mechanism will not actuatethe carriage releasing mechanism; and there is a similar cut-out 7 7 aat the left-hand end of the universal bar.

The stop retracting, or unsetting de vices as they are sometimes called,comprise a cam arm or wiper 100 horizontally disposed and pivoted at its"right-hand end, which is bent laterally rearward, on a pivot pin 101mounted on a lug 102 on the righthand face of the hood- 37 andprojecting downward from said lug. The arm 100 extends leftward acrossthe front of the lower part of the comb plate 41 and under theoverhanging portion thereof. Said comb plate is provided near itsleft-hand free end portion with a double cam face 103 which is in linewith the stop portions 31 of the column stops. At itsleft-hand end thearm 100 is provided with a rearward extension or finger 104, best shownin Fig. 9, which serves as a guide and support for the wiper member100104 in cooperation with a guide, slot 105 out in the left-hand endofthe comb 41 and a. second guide slot 106 formed or cut in a thickenedportion of the hood 37 at its left-hand side (Fig. 9). When the cam orwiper 100 is swung horizontally back and forth it is preventedfromsaggin "or getting out of position by the guide n'ger104 co-operat-fling with itsguide' slots. Said cam member is actuated by a lever 107arranged at the left of the setof] levers 48'. and generally conformingin shape to said levers, being guided by" the left-hand one of the slots52, but having a separate pivot 108 supportedby the left-hand arm 38.The upper portion orhead of'the lever 107' difi'e'rs, however, fromtheheads 49' of'the levers'48, said lever 107 having awider head or endportion 109 which ts .in a special "wide slot 44 in the comb plate 41.Below the head 109 the lever 107 is provided "with a forwardly extendinghook 110 whoseiupturned end lies under the" cam portion 103 of the arm100, said cam portion being undercut to provide a shoulder 111, withwhich the hook 110 may co-operate. It will be seen, more especially fromFig. 8, that the upturned end of the hook 110 lies'just in front of theshoulder 11 1 while the lower end of the head 109 liesjust behind thearm 100, there being an open space Y 112 between the head or blade andthe hook.

The construction is such that "the arm 100 'isthus loosely connectedwith the lever 107 bywhich it is positively actuated in bothdirections,,said arm being adapted tobe swung'forward by the lower endof the head 109 and being adapted to be-swung backward by the action ofthe hook 110 on the shoulder 111. The means for'zop era'ting thelever107 for this purposecomprises a slide'rod 113 which is similar inconstruction to the slide rod 61 and is, ar

rangedat the left-hand end otthe setof;

slide rods. The slide rod 113 is provided with an upright actuatingportionllopposite the lower end of-the lever 107 and lso with a guideportion 115, the rear end hand lower an upper slots 68 and 67 inthe bar64. The slide rod113 extends forin-the leftforward of or unsetl'key 116is pushed; in, it will slide the rod '113 rearward,.causing it toactuatethe lever 107 which will be swung-omits lease of the carriage.

of the'lever'107 swings forward from the pivot 108. Said lever107. beingopposite the left-ha'nd cut-out 77 in the universal bar 77 will notactuate said universal bar and consequently will not efi'ect, there: Asthe upper arm position shown in Figs. 1 and 7 to the position shown inFig. 8,the blade .109 acting against the arm 100 will'swingthe latter onits pivot 101 and carry the-double cam or wiper 103 into posiltion forco-opeim' co 'umn stops'31 e-' tion with the projects portion of said"rod and its guide. ortion; 115' co-operatin respectively with t e leftlow their stop portions 31. Consequently if the operator maintain theunset key 116. pressed in, andat the same time release the carriagebyhand and move it back and .forth or; fromone sideto the other, the

double cam or wiper 103 will act on the projected or set column stops 31to slide them back'on their stop bar or towards the front ofthe machineto unset orinoperative position, thus clearing the tabulating mechanismso that a new setting of the c0 1 liability o actuating the wrong keysby mistake is reduced.

. will be seen that by our present invention. .there is provided anunusually compact, and simple decimal tabulating mechanismwhichincludesdevices for setting the column stops and also retracting orunset- .ting them; that'said tabulating mechanism is readily attachableto thet pewriting ma chine and detachable there rom; and that it.doesnot greatly add apparently tothe size-of the machine since t ecolumn sto devices instead of bein outside as is usua in this-case arearrange within the machine, so to-speak, being disposed underthe carriageand between it and its bed plate or trough.v v. i
